"What would be funny, Flossie?" asked Freddie, and one look at the two
smaller Bobbsey children would have told you that they, too, were
twins. In fact the four Bobbseys were twins--that is there were two
sets of them--Bert and Nan, and Flossie and Freddie. "What would be
funny?" Freddie wanted to know. "Tell me! I want to laugh."

"Yes, you generally do want to laugh, little fireman!" and Bert
Bobbsey laughed himself as he gave his small brother the pet name that
Daddy Bobbsey had thought up some time ago. "But, as Flossie says, it
would be funny to see a snow man rolling around in the drifts to make
himself bigger," went on Bert.

"But you said he'd get bigger if we threw snowballs at him," insisted
Nan.

"And he will," went on Bert. "You see, a snowball gets bigger when you
roll it around the yard, because more snow keeps sticking to it all
the while. And if we make a snow man and then throw little snowballs
at him, these snowballs will stick to him and he'll grow bigger, won't
he?"

"Oh, I didn't know you meant _that_ way!" and now Nan, herself,
began to laugh. Of course Flossie and Freddie joined in, though I am
not sure that they knew what the joke was all about, but they were
having fun in the snow and that was all they cared for.

It was a fine snow storm, at least for the Bobbsey twins and the other
children of Lakeport. It was not too cold, and the white flakes had
come down so fast that there was now enough snow to make many snow men
and snowballs, and leave plenty for coasting down hill.
